         The <code class="methodname">DbEnv::get_ext_file_dir()</code> method returns
         the directory location where external file data is stored. The default
         location can be set using <a class="xref" href="envset_blob_dir.html" title="DbEnv::set_ext_file_dir()">DbEnv::set_ext_file_dir()</a>. Use this method only
         if the database was opened in an environment. If the database
         was not opened within an encompassing environment, use
         <a class="xref" href="get_blob_dir.html" title="Db::get_ext_file_dir()">Db::get_ext_file_dir()</a> instead.
     </p>
      <p>
         The <code class="methodname">DbEnv::get_ext_file_dir()</code> method always
         returns 0 to indicate success.
